Key takeaways
- Obstructive Sleep Apnoea (OSA): This is the most common form, affecting an estimated 1.5 million adults in the UK, with many more remaining undiagnosed. It happens when the soft tissues at the back of your throat relax and collapse during sleep, physically blocking your airway.
- Central Sleep Apnoea (CSA): This type is less common. It occurs when your brain fails to send the correct signals to the muscles that control your breathing. There's no physical blockage; the system simply pauses.
- Complex (or Mixed) Sleep Apnoea: This is a combination of both OSA and CSA.
- Loud, persistent snoring
- Pauses in breathing, often noticed by a partner

WeCovr's guide to sleep apnoea testing and private treatment
A good night's sleep is the cornerstone of good health. Yet for millions in the UK, restful sleep is a nightly battle. If you or your partner suspect that loud snoring, gasping for air, and constant daytime fatigue are more than just signs of a busy life, you could be dealing with sleep apnoea.
This guide will walk you through everything you need to know about this common but serious condition. We’ll cover the symptoms, the risks of leaving it untreated, and the crucial differences between the NHS and private pathways for diagnosis and treatment. Most importantly, we'll clarify what you can—and can't—expect from your private medical insurance policy.
What Exactly is Sleep Apnoea?
Sleep apnoea is a sleep disorder where your breathing repeatedly stops and starts. The word "apnoea" literally means "without breath." These pauses can last from a few seconds to over a minute and can happen hundreds of time a night, often without you even realising.
This disruption starves your brain and body of oxygen, forcing you to briefly wake up to restart breathing. You won't remember these awakenings, but they wreck your sleep quality, leaving you exhausted the next day.
There are three main types of sleep apnoea:
- Obstructive Sleep Apnoea (OSA): This is the most common form, affecting an estimated 1.5 million adults in the UK, with many more remaining undiagnosed. It happens when the soft tissues at the back of your throat relax and collapse during sleep, physically blocking your airway.
- Central Sleep Apnoea (CSA): This type is less common. It occurs when your brain fails to send the correct signals to the muscles that control your breathing. There's no physical blockage; the system simply pauses.
- Complex (or Mixed) Sleep Apnoea: This is a combination of both OSA and CSA.
Because it's so common, this guide will focus primarily on Obstructive Sleep Apnoea (OSA).
Are You at Risk? Key Symptoms and Risk Factors
Sleep apnoea can affect anyone, including children, but certain factors increase your risk. Recognising the signs is the first step toward getting help.
Common Symptoms of Sleep Apnoea:
- Loud, persistent snoring
- Pauses in breathing, often noticed by a partner
- Gasping, choking, or snorting sounds during sleep
- Waking up suddenly feeling short of breath
- Excessive daytime sleepiness (feeling tired no matter how long you've been in bed)
- Morning headaches
- Difficulty concentrating or memory problems ("brain fog")
- Feeling irritable or having mood swings
- Waking up frequently during the night to urinate
- Dry mouth or sore throat upon waking
Key Risk Factors:
| Risk Factor | Why It Matters |
|---|---|
| Excess Weight | This is the single biggest risk factor. Excess fat deposits around the upper airway can obstruct breathing. |
| Being Male | Men are two to three times more likely to have sleep apnoea than women. |
| Age | The risk increases as you get older, particularly for those over 40. |
| Neck Circumference | A larger neck size (over 17 inches for men, 16 inches for women) often means a narrower airway. |
| Family History | Having family members with sleep apnoea increases your risk. |
| Alcohol & Sedatives | These substances relax the throat muscles, worsening airway collapse. |
| Smoking | Smoking causes inflammation and fluid retention in the upper airway, narrowing it. |
| Nasal Congestion | If you have difficulty breathing through your nose, you're more likely to develop sleep apnoea. |
The Hidden Dangers: Why You Shouldn't Ignore Sleep Apnoea
Many people dismiss snoring as a simple annoyance, but true sleep apnoea is a serious medical condition with significant long-term health risks. The repeated drops in blood oxygen levels put immense strain on your cardiovascular system.
Untreated sleep apnoea is strongly linked to:
- High Blood Pressure (Hypertension): The sudden drops in oxygen trigger a stress response, raising your blood pressure.
- Heart Disease: Increased risk of heart attacks, heart failure, and irregular heartbeats (atrial fibrillation).
- Stroke: Studies show a strong link between severe OSA and an increased risk of stroke.
- Type 2 Diabetes: Sleep apnoea can interfere with your body's ability to use insulin effectively, leading to insulin resistance.
- Daytime Accidents: The severe fatigue caused by OSA significantly increases the risk of accidents while driving or operating machinery. The Department for Transport estimates that driver fatigue is a factor in up to 20% of serious road accidents.
- Mental Health Issues: The constant exhaustion and poor sleep can contribute to depression and anxiety.
Given these risks, getting a prompt and accurate diagnosis is not just about feeling better—it's about protecting your long-term health.
Getting a Diagnosis: The NHS vs. Private Pathways
If you suspect you have sleep apnoea, you have two main routes to a diagnosis in the UK: the NHS and the private sector.
The NHS Pathway
- GP Appointment: Your first step is to see your GP. They will ask about your symptoms, lifestyle, and medical history. They may use a screening tool like the Epworth Sleepiness Scale to gauge your level of daytime sleepiness.
- Referral: If your GP suspects sleep apnoea, they will refer you to a specialist sleep clinic at a local hospital.
- Waiting List: This is often the most significant hurdle. According to NHS England data, waiting times for diagnostic tests can vary dramatically by region, often stretching for many months. As of mid-2024, millions are on NHS waiting lists for various procedures, and sleep studies are no exception.
- Sleep Study: Once you reach the top of the list, you'll undergo a sleep study. This is usually an at-home test where you wear monitoring equipment overnight. In some complex cases, you might be admitted for an in-clinic study.
- Results & Treatment Plan: A specialist will analyse the results and confirm a diagnosis. If you have OSA, the standard NHS treatment is a CPAP machine, which will be provided to you on a long-term loan.
The NHS provides excellent care, but the waiting times for a diagnosis can be a source of significant stress and can prolong the health risks associated with untreated apnoea.
The Private Pathway
The private route offers a much faster alternative, allowing you to bypass NHS waiting lists and take control of your health journey.
- Referral: You can still ask your GP for a private referral to a respiratory or sleep specialist. Many private medical insurance policies require a GP referral. Alternatively, some private clinics allow for self-referral.
- Consultation: You will be able to see a consultant specialist, often within a week or two. They will conduct a thorough assessment.
- Private Sleep Study: The consultant will arrange a sleep study, which can typically be done within days. Most private tests are convenient at-home kits delivered directly to you.
- Rapid Diagnosis: The results are analysed quickly, and you'll have a follow-up consultation to discuss the diagnosis and treatment options, often within two weeks of your initial enquiry.
The primary benefits of the private pathway are speed and choice. You get answers fast, allowing you to start treatment sooner and mitigate the health risks.
Private Sleep Apnoea Testing Explained
Private sleep studies are designed to be as convenient and unobtrusive as possible while providing highly accurate data.
What Does a Sleep Study Measure?
Whether at home or in a clinic, a sleep study (polysomnography) measures key biological signals, including:
- Airflow: To detect pauses in breathing.
- Breathing Effort: To see how hard your chest and abdomen are working to breathe.
- Blood Oxygen Levels (Oximetry): To measure the dips in oxygen saturation (a key indicator of apnoea severity).
- Heart Rate: To monitor cardiovascular strain.
- Snoring Intensity: To correlate sound with breathing events.
- Sleeping Position: To see if apnoeas are worse in certain positions (e.g., on your back).
At-Home vs. In-Clinic Sleep Studies
For most suspected cases of OSA, an at-home study is the standard first-line investigation in both the NHS and the private sector.
| Feature | At-Home Sleep Study | In-Clinic Sleep Study |
|---|---|---|
| Convenience | High. The equipment is delivered to your door, and you sleep in your own bed. | Low. Requires an overnight stay in a hospital or clinic. |
| Environment | Natural. Provides a more typical picture of your sleep patterns. | Unfamiliar. Can sometimes be difficult to sleep normally with wires and a new environment. |
| Data Collected | Measures key respiratory and cardiac signals. Sufficient for diagnosing most OSA cases. | More comprehensive, may include brainwave monitoring (EEG) to assess sleep stages. |
| Best For | Suspected uncomplicated Obstructive Sleep Apnoea (OSA). | Complex cases, suspected Central Sleep Apnoea (CSA), or if the at-home test is inconclusive. |
| Typical Private Cost | £300 – £600 | £1,000 – £2,500+ |
Does Private Medical Insurance Cover Sleep Apnoea Testing?
This is a critical question, and the answer requires understanding a fundamental principle of private medical insurance UK.
Important: Standard UK private medical insurance (PMI) is designed to cover acute conditions—illnesses that are new, unexpected, and likely to be resolved with a single course of treatment. It does not cover chronic conditions, which are long-term and require ongoing management. Sleep apnoea is classified as a chronic condition.
Furthermore, PMI policies almost always exclude pre-existing conditions. This means any condition for which you have had symptoms, advice, or treatment before your policy started will not be covered.
So, where does that leave sleep apnoea testing?
- Diagnostic Cover: Many PMI policies offer excellent cover for diagnostics. If you develop symptoms after your policy has started, your insurance will likely cover the initial consultation with a specialist and the diagnostic tests (like a sleep study) required to find out what is wrong.
- The "Chronic" Catch: The crucial point is what happens after the diagnosis. Once sleep apnoea is confirmed, your insurer will classify it as a chronic condition. This means while they may have paid for the diagnosis, they will not pay for the ongoing treatment (like a CPAP machine).
- Pre-existing Symptoms: If you had symptoms of sleep apnoea (e.g., your partner told you that you snore loudly and stop breathing) before you took out your policy, the entire condition, including the diagnostic tests, would be excluded as pre-existing.
Here's how it might work in practice:
Real-Life Example:
- Sarah, 45, has had a PMI policy for three years. Over the last six months, she has started feeling exhausted and her husband has noticed she gasps in her sleep. These are new symptoms.
- She gets a GP referral. Her PMI provider authorises a consultation with a private respiratory specialist and an at-home sleep study.
- The tests cost £550, which her insurer pays in full.
- The results confirm moderate OSA. The specialist recommends CPAP therapy.
- Because OSA is a chronic condition, Sarah's insurer will not cover the cost of the CPAP machine or ongoing supplies. The cover for this condition ends with the diagnosis. Sarah would then need to purchase the CPAP machine herself or go back to the NHS.
An expert PMI broker like WeCovr can help you find a policy with robust diagnostic benefits, ensuring you can at least get a swift, private diagnosis, even if the long-term treatment falls outside the scope of cover.
Private Treatment for Sleep Apnoea: CPAP and Other Options
Once diagnosed, the goal of treatment is to keep your airway open while you sleep.
CPAP Therapy: The Gold Standard
Continuous Positive Airway Pressure (CPAP) is the most effective and widely used treatment for moderate to severe OSA.
- How it works: A small, quiet machine sits by your bedside. It delivers a steady stream of pressurised air through a tube to a mask that you wear over your nose or nose and mouth. This gentle air pressure acts like a "splint," keeping your airway open and preventing it from collapsing.
- Effectiveness: For most people, the results are immediate and life-changing. From the very first night, the apnoeas and snoring stop. You'll wake up feeling refreshed for the first time in years.
- Private CPAP Costs: If you are diagnosed privately and choose to purchase your own equipment, the costs are approximately:
- CPAP Machine (illustrative): £500 – £1,200 (for an automatic, auto-titrating machine which is the modern standard).
- Mask (illustrative): £80 – £150 (this is a personal item and may need replacing every 6-12 months).
- Ongoing Supplies: Hoses, filters, and mask cushions will need periodic replacement.
Will Private Health Insurance Pay for a CPAP Machine?
In almost all cases, no. As explained above, CPAP is a treatment for a chronic condition. Standard private health cover in the UK does not pay for the long-term management of chronic conditions. The cost of the machine and its supplies will be your responsibility.
However, paying for the diagnosis privately can still be hugely beneficial, as it allows you to then take that private diagnosis back to your NHS GP. With a confirmed diagnosis in hand, your GP may be able to fast-track you onto the NHS pathway for receiving a CPAP machine, potentially saving you months on a diagnostic waiting list.
Other Treatment Options
While CPAP is the most common treatment, other options may be suitable, particularly for mild OSA or for those who cannot tolerate CPAP.
- Mandibular Advancement Devices (MADs): These are like dental mouthguards that push your lower jaw and tongue forward, helping to keep the airway open. They are often effective for mild to moderate OSA. A custom-made device from a dentist can cost between £500 and £1,500.
- Lifestyle Changes: These are crucial for everyone with sleep apnoea, either as a standalone treatment for mild cases or in conjunction with other therapies.
- Positional Therapy: For some people, apnoea only occurs when they sleep on their back. Special devices or pillows can help you stay on your side.
- Surgery: In specific cases, surgery to remove excess tissue from the throat (such as Uvulopalatopharyngoplasty or UPPP) may be an option, but it is less common and reserved for when other treatments have failed.
Lifestyle Changes: Empowering Yourself to Breathe Easier
Making positive lifestyle changes can have a dramatic impact on sleep apnoea symptoms, and in some cases of mild OSA, may even resolve the condition.
- Manage Your Weight: Even a 10% reduction in body weight can reduce the severity of sleep apnoea by over 25% for many people. It's the single most effective lifestyle change you can make.
- Get Active: Regular moderate exercise, such as a brisk 30-minute walk five days a week, helps with weight loss and improves muscle tone in the upper airway.
- Avoid Alcohol Before Bed: Alcohol relaxes your throat muscles, making airway collapse more likely. Avoid it for at least four hours before sleeping.
- Quit Smoking: Smoking irritates and inflames your airway. Quitting will reduce this inflammation and improve your overall health immeasurably.
- Change Your Sleep Position: Try to sleep on your side rather than your back. You can use pillows to prop yourself up or try sewing a tennis ball onto the back of a t-shirt to make back-sleeping uncomfortable.
